MACHlNE FOR CALENDERING PAPER;

SPECIFICATION forming part of Letters Patent No.26,080, dated April 1, 1884.

Application filed February 1, L884. (No model.)

To all whom it may concern Be it known thatL'MosEs SoLINc-nn, of the city, county, and State of New York, haveinvented certain new and useful. Improvements in Machines for Calendering Paper, of which the following is a specification.

This invention has reference to an improved machine for calendering or finishing paper at ing and unwinding the paper.

It consists, secondly, of means for registering the number of sheets passed through the machine.

In the accompanying drawings, Figure 1 represents a rear elevation, partly in section, of my improved calendering -machine, and Figs. 2 and 3 are elevations of the same taken from opposite sides. a Similar letters of reference indicate corresponding parts.

A A represent the supporting-standards of my improved. paper calendering machine. The standards A A are provided with vertical guide-recesses a a, for the bearings of the three calendering-rolls. the upper and intermediate steel rolls, B and B, and a paper-roll, B, which are arranged one below the other. The upper and intermediate rolls, B and B, are made hollow, and provided with hollow axles b, that extend through their bearings 12. The lower .1 roll, B, is made of a series of paper disks that are tightly compressed between the heads of the roll and then turned off true, so as to form a. solid smoothly-surfaced roll. The'rolls B B B revolve in contact with each other, the pressure between the rolls being increased or decreased by means of weighted levers G, that are pivoted to the lower rear part of the supportingstandards A A, and connected by upright pivot-rods O with levers .0, that are pivoted to the top part of the frame. The top levers, 0 press upon the rounded-off upper ends of vertically guided rods. O,-that press upon the bearings b ofthe upper roll, B. I By adjusting the weights of the lower levers, G O, nearer to or farther away from their pivots the pressure on the calendering -rolls B B B is diminished or increased. The hollow steel rolls B B are heated by means of central gas-jet pipes, at d, that pass longitudinally through the rolls, the air required for combustion being drawn in through the hollow shaft b at that end where the gas-pipe enters, and the products of combustion discharged through the hollow shaft 12 at the opposite end of the rolls. The gas-jet pipes d are connected in any suitable manner to the gas-supply pipes 11, which latter have stopcocks d, toregulate or shut off the supply of gas. the vertical gas-supply pipes d through small openings at above the stop-cocks (1, as shown in Figs. 2 and 3, and mixed with the gas, so that the proper heatingjets are obtained. The motion is transmitted to the calenderingrolls B B B from a power-shaft, D, by suitable transmitting gear-wheels, which are arranged in such a manner that a comparatively slow motion'is imparted to the lower paperroll, B a quicker motion to the intermediate A certain quantity of air is drawn into roll, B, and a still quicker motion to the upper roll, B.

The roll of paper to be calendered is placed on a shaft, E, that turns in bracket-bearings at one end of the machine, said shaft being provided witha pulley,.e, to which a brakeshoe, 6, that is operated by a hand-wheel.

shaft, 6 can be applied at will. The threaded end of the shaft 0 engages a nut on the shank of the brake-shoe, so as to apply it to or remove it from the friction-pulley of the unwinding-shaft E, as required. The paper is conducted from the unwindingshaft E over the tension-rollers E, and from the same through between the upper steel rolls, B B,

.if both sides are to be calendered,'-and between the intermediate steel roll, B, andthe lower paper-roll, Bflwhen one side only has to be finished. The paper is wound up in the usual manner on a shaft, F, that receives its motion by transmitting gear-wheels ff from the power-shaft D. The winding-up-shaft F is provided' with a fixed friction-disk, f, and a laterally-movable disk, J, the hub f of the latter being grooved and engaged by the forkshaped end of a fulcrumed lever, f". The op posite end of the lever f is engaged by the threaded end of a short hand-wheel shaft, f,

which turns in bracket-bearings of the supporting-frame, as shown in Fig. 1. The movable friction-disk f is applied more or less tightly or released from the fixed disk f so as 5 to regulate the speed of the Windingup shaft. The end of the paper is clamped to the wind ing-up shaft in any approved manner, but so that the shaft can be withdrawn from the roll of paper after it has been wound up.

When continuous paper is to be calendered on the machine, the length of the same is registered by means of a registering mechanism of any approved construction. That shown in the drawings consists of a fixed dial, and I5 apointer, applied to a worm-gear, 9", said gear meshing with a worm, g, at the end of a short horizontal shaft, 9, that turns in bearings of one of the standards A, the opposite end of the shaft being provided with radial 2O arms that are successively engaged by a projecting pin or stud, g, on the gear-wheel that imparts rotary motion to the lower pa per-roll, B as shown in Fig. 1.

WVhen sheets are to be calendered, they are fed over a table, H, supported on detachable brackets H at the feeding end of the machine,

to apair of feed-rolls, h h, one of which receives rotary motion by a belt-and-pulley transmis- .sion from the shaft of the paper-roll B Back of the upper feed-roll, h, is arrange on thetable H a transverse deflectingplate, k, that guides the sheet of paper upward and over a transverse roller, if, supported in bearings at the rear end of fulcrumedlevers H the front ends of which are acted upon by springs h. The

sheet of paper is next taken up by the calendering-rolls B B, which exert a tension on the sheet of paper, that is stretched taut between the feed-rolls h h, roller If, and calendering- The levers H are thereby lowered, and a pawl, h, pivoted to the rear end of one of the levers H dropped intoaratchet-wheel, it When the sheet has passed over the roller h the springs h" raise the levers H and cause '45 thereby the turning of the ratchet-wheel for the distance of one tooth. The shaft of the ratchet-wheel h actuates, by a transmitting worm wheel and gear, h h a pointer, h that indicates on a dial, h, the number of sheets 5 which have passed through the machine. In this manner the sheets that are calendered on the machine are registered in a regular manner. The feed-table and the entire registering mechanism may be removed or applied to the standard A at a level with the paper-roll B",in which latter case the sheets are calendered on one side only.

I am aware that heated pressure-rolls have been used heretofore for calendering paper and other fabrics, and I therefore do not claim the same broadly; neither do I claim' the device for registering thelength of the continuous paper-roll passing through the machine, as such registering devices are .old and well known; but I do claim the combination of heated calenderingrolls with alower revolving paperroll, whereby paper may be calendered at one or both sides, and also the device by which single sheets may be registered.

Having thus described my invention, I claim as new an d desire to secure by Letters Patent- 1. In a paper-calendering machine, the combination ofa heated pressure-roll, intermediate heated roll, and alower paper-roll,with means for unwinding and with means for winding up the paper, whereby the paper may be finished at one or both sides, according as the same is passed between the lower and intermediate rolls, or between thenpper and intermediate rolls, substantially as and for the purpose set forth.

2. Inapaper-calendering machine, the combination of an upper heated pressure-roll, an intermediate heated roll, a lower paper-roll, means 'for unwinding the paper, means for winding up the paper, and friction-brakes ap plied to the unwinding and winding-up shafts, whereby the paper is moved at aproperly-regulated speed through the calendering-rolls, substantially as set forth.

3. The combination, with the calenderingrolls, of a sheet-registering mechanism consisting of a feed-table having revolving feedrolls, deflecting-plate back of the feed-rolls, tensionroller supported 011 oscillating and spring-acted levers, and means whereby the oscillations of the levers are transmitted to a registering dial and hand, substantially as set forth.

In testimony thatI claim theforegoing as my invention I have signed my name in presence of two subscribing witnesses.
